Is it just me who keep getting some sort of strange error on searches on :en:?
The symptoms so far include showing the Google/Yahoo boxes and an odd error message indicating some sort of bad return from an IP in the [10.*.*.*] range. My IP knowledge is rusty: is that a private range?
Sorry I can't be more precise: the error sometimes goes away when I try again, and did this time :-(
At the moment, we have three search servers: maurus (10.0.0.16), vincent (10.0.0.17) and coronelli (10.0.0.230). For reasons not quite understood, they sometimes hang, accepting connections but closing them immediately. Yesterday, Brion set up an hourly restart of the daemons to mitigate this. Most of the search errors before then were probably due to this problem. The server you get for any given query is random, that's why it often goes away when you try again.
The other potential problem is a timeout: if the search server takes more than 3 seconds to respond, then an error will be returned. This could happen due to high load, or due to random temporary events. Looking at the profiling data I gathered yesterday, it's likely that this has been happening a fair bit during peak time.
